Is a Thermostat Replacement in Your Future?

Thermostats are an important part of your home’s infrastructure that you may not think much of until they experience an issue. Often, older thermostats are working past their estimated lifespan, and that is when they begin to show signs they may warrant a replacement.

No matter the age of your thermostat, look out for:

  • Inaccurate Readings: The device displays a temperature that doesn’t match the actual air in the room.
  • Unresponsive Interface: The screen stays blank or buttons fail to trigger the air conditioner.
  • Short Cycling: Your HVAC system turns on and off too frequently due to faulty sensor data.
  • High Energy Bills: An outdated controller causes your unit to run longer than necessary.
  • Obsolete Technology: Older manual sliders lack the precision of modern digital controls.

Nick H did a fantastic job. He came on a Friday afternoon in August and replaced the part that was ordered, eliminating the freon leak. He spent about 5 hours completing the job. He is very knowledgeable and professional and I was very impressed.

My technician James did an incredible job. I initially had a membership with a different company. (Assured Comfort) who came out to do maintenance but would check the drain connected to my AC, it clogged and flooded and ruin my ceiling. They sent two technicians in three days that couldn’t help me, prolonging the process of repairing my ceiling because there was still water inside my AC, and Duct that they failed to fix. So what did I do? I called RS Andrews. Our technician James responded out, made sure everything was clear and operable, documented everything correctly, and referred us to the department who’ll be out to make the repairs. James was very knowledgeable and they officially have a new customer. Might I add that they DO check drains during maintenance unlike other companies but I would definitely recommend RS Andrews.

Paul and his associate were able to fix a problem that several people had turned down as being “too hard to figure out” and “would take too much time”. So I was very pleased that they were able to find the problem and fix it! I would definitely hire them again and also would not hesitate to refer to others.

Pau had to reinstall our new toilet located on our home’s second floor. He has been to our home before and always installs correctly, efficiently and is very respectful of our homes hardwood floors and interior carpeting. We are always very, very satisfied with Pau for a professional repair or a new install!

Huge thank you to Terrell Thomas! After spending the day dealing with multiple issues, losing my AC was the last thing I needed. Terrell came out after hours, quickly diagnosed the problem, explained everything in a way I could understand, and got my AC running again. He never rushed the job and made sure everything was working before he left. Professional, knowledgeable, and courteous from start to finish. I highly recommend him and really appreciate the excellent service. Thank you again, Terrell!

5/5 Stars
Our AC went out, and Nick was absolutely fantastic. Not only did he diagnose and fix our current issue, but he also discovered several installation flaws from when the system was put in a few years ago. He spent several hours meticulously bringing our unit back up to proper condition—even resolving a long-standing airflow issue in our house that we’ve had to deal with for years. Nick was super smart, super nice, and extremely helpful. I can't recommend this company and Nick highly enough!

I use R.S. Andrew’s often for electrical and plumbing needs. I have a favorite technician in both areas and today I was visited by my favorite friendly plumber Johnathan Chapman! Not only is he SUPER informative and thorough, he’s the nicest person ever. I not only get my needs addressed when he comes but I always feel like I learn a thing or two!! LOL!!

    Heater on the fritz? Frustrated with plumbing problems? R.S. Andrews is just a call away!
